Since all bootstrap files are preloaded, I tried to remove some files that I don't think I will be using, especially the folder bootstrap/assets/js/ckeditor, which is more than 3MB. I'm not sure if this is good or if it won't cause problems in the future, but it helped the page loading speed.

But i have still the feeling that Yiibooster is too slow. Compare to a fresh generated site the difference is pretty big. :-(

exactly 24.46 requests per second is what the same app that i'm testing can process in my localhost when using yii's default theme with the blueprint css framework.

i suppose that things will be different when a project become more complex and after use of more booster components. maybe we got to test that later & compare with other css themes or frameworks. but for now. the beauty of my fresh app thanks to booster & twitter's bootstrap is worth
